POST使用捲曲不同的數據類型

Question

我生成一些XML（實際上谷歌KML文件）

$kml = array('<?xml version="1.0" encoding="UTF-8"?>'); 
$kml[] = '<kml xmlns="http://earth.google.com/kml/2.1">'; 
$kml[] = ' <Document>'; 

我做它的一個字符串

$kmlOutput = implode("\n", $kml); //Join array elements with a string 

然後我製造陣列

$data = array('code' => 'somecode', 'xml' => $kmlOutput); 

然後我發送我的cURL數據

//設置捲曲

$ch = curl_init($URL); 
curl_setopt($ch, CURLOPT_POST, true); 
//curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml')); 
curl_setopt($ch, CURLOPT_POSTFIELDS,$data); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, 8); 
$output = curl_exec($ch); 

/** 
* Check for some errors (omitted here) 
*/ 
curl_close($ch); 

upload.php的另一臺服務器

/* MAIN CODE*/ 
if ($_SERVER['REQUEST_METHOD'] === 'POST'){ 
    print "\n\n"; 
    echo "DEBUG: Vardump Post"; 
    var_dump($_POST); 
    echo "DEBUG:"; 
    var_dump($_FILES); 

    if ($_FILES["file"]["type"] == "text/xml" && ($_FILES["file"]["size"] < $maxSize)){ 
     if ($_FILES["file"]["error"] > 0){ 
      echo "Error: (Return Code: " . $_FILES["file"]["error"] . ")<br />"; 
     } else { 
      echo "Code: ".$_POST['key']. "<br />"; 
      echo "Upload: " . $_FILES["file"]["name"] . "<br />"; 
      echo "Type: " . $_FILES["file"]["type"] . "<br />"; 
      echo "Size: " . ($_FILES["file"]["size"]/1024) . " Kb<br />"; 
      echo "Temp Stored in: " . $_FILES["file"]["tmp_name"]. "<br />"; // temporary copied files disappears when the script ends 


      move_uploaded_file($_FILES["file"]["tmp_name"],$dir . $_FILES["file"]["name"]); 
      echo "Stored in: " . $dir . $_FILES["file"]["name"]; 

上。然而後續代碼var_dump（$ _ FILES）;甚至var_dump（$ _ FILES [「code」]）;返回空嗎？

-Am我在這裏錯過了什麼？ - 我可以發送兩種類型的數據嗎？

你不能因爲你沒有上傳任何文件

要上傳您需要使用@符號後面跟你的文件的位置的文件通過$_FILES得到它

$data = array('code' => 'somecode', 'xml' => "@". $PATH_TO_XML_FILE); 

用戶也可以直接直接上傳這樣

curl_setopt($ch, CURLOPT_POSTFIELDS, $kmlOutput); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/xml")); 

例

$xml = __DIR__ ."/Pages.xml"; //full part to XML 
$data = array('code' => 'somecode', 'xml' => "@$xml"); 
$ch = curl_init($URL); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, 8); 
$output = curl_exec($ch); 
echo $output ; 

在遠程頁面

var_dump($_POST,$_FILES);
